[Gastric chemistry in the pathology of the cardiohiatal sector]

Study of gastric chemistry in patients with cardiohiatal anomalies is an efficient test for distinguishing those cases that can evolution with complications and thus require surgical intervention. From a total of 720 patients affected with this pathology and observed between 1976 and 1982, a group of 164 were submitted to this study, 72 resulted with gastric acid rates higher than normal. 55% of these patients were operated. It is an easy test to realize in any service of Pediatric Surgery.
